引入了随机环境中具有迁移的分枝过程,讨论了该模型的马氏性、条件概率母函数和条件期望,以及各代迁移粒子数、各代单个粒子产生的后代数的条件期望的性质.
Branching processes with migration in random environments are introduced in this paper. Its Markov propertity,conditional generating function and conditional expectation on random environments are obtained. Also the properties of conditional expectations on random environments of the number of particles migrating in each generation and that of descendants produced by a single particle in each generation are discussed.
